A Control Approach and Design Consideration of PV/Diesel Hybrid Distributed Generation System Using Dual Voltage Source Inverter for Weak Grid

In this paper, a control and design consideration of PV/diesel hybrid distributed generation system using dual inverter for weak grid is presented. The dual inverter employs a combination of a voltage controlled voltage source inverter (VCVSI) and a current controlled voltage source inverter (CCVSI), connected in series on the DC side and in parallel on the AC side. This system is able provide an uninterruptible power supply (UPS), load voltage stabilization, unity power factor correction, maximum power point tracking (MPPT), and demand side management (DSM). To verify the proposed system, a comprehensive evaluation with theoretical analysis and experimental results is presented
